Installation of the barrier is fairly straight forward. First, dig near the bamboo plant to determine how deep the existing roots extend into the ground. Once the depth of the roots is determined it is recommended that a barrier is chosen that is approximately 12” deeper than the depth of the bamboo roots. For example, if the bamboo plant's roots extend 18” into the ground a 30” barrier should be chosen. The reason for going deeper than the existing roots is when the barrier is installed the roots may angle downward attempting to go around the barrier. Although the roots are much more likely to extend upward there is a chance that they could go down. 12” of extra depth on the barrier provides more protection and greatly reduces that chance of the bamboo roots going under the barrier.
Once the appropriate height of barrier has been chosen, dig a trench around the bamboo planting area with a depth that is 2” less than the height of the barrier. For example, if you are installing a 30” barrier, dig a 28” trench. This is to allow 2” of the material to stick above the surface forcing any bamboo rhizomes which are inclined to “jump” the barrier to surface and jump up and over the barrier. The gardener will then have a visual of the jumping rhizome and will have a chance to clip as necessary to prevent spread of the plant.
Cut the material to the appropriate length, place the barrier in the trench and be sure to overlap the material 4 feet at the seam to make a complete circle. Use HDPE seam tape to secure the two pieces together.
Finally backfill the trench around the material. The bamboo planted within the barrier area will now be well contained and if the roots are trimmed properly will not leave the designated area.
